Quantitative Ashwagandha Testing
Ashwagandha Withanolides
Scientific-name context: Withania somnifera
Ashwagandha Withanolides covers 8 analytes with individual quantitative results for most raw materials, intermediate ingredients, and finished products.
Standard analysis uses UHPLC-DAD. MS or MS/MS analysis is available for an additional charge when ultra-low detection limits are needed.
Ordering reference: Test Code 105
Defined Coverage
One defined quantitative profile
The laboratory will confirm the matrix, reporting basis, sample requirements, timing, and price before testing begins.

Profile Rationale
Why these eight ashwagandha markers?
The panel brings together commercially useful, chemically defined markers without assuming that every target is dominant. Withaferin A and withanolide A are widely used analytical markers; withanosides IV and V, 12-deoxywithastramonolide, withanolide B, and withanone broaden the composition view, while withaferin B extends the named coverage.
Which compounds are most abundant varies with plant part, cultivar, growing conditions, extraction, and formulation; published root and leaf materials can show markedly different withaferin A and withanolide A patterns. This is a defined eight-compound profile, not an exhaustive measurement of every ashwagandha constituent, so the result should not be represented as total withanolides or as equivalent to a USP, AOAC, or other separately defined calculation without matching that exact scope.
Method & Reporting
Quantitative results in the reporting basis you need
Standard analysis
The in-house validated method runs standard on UHPLC-DAD. Every analyte listed in the profile is quantitatively reported.
Optional sensitivity
MS or MS/MS analysis is available for an additional charge when a project requires ultra-low detection limits. Confirm feasibility and pricing before submission.
Reporting units
The default unit is w/w%. Results may also be reported as mg/g, mg/mL, or mg/unit when the submission supports the requested basis.
Matrices & Sample Quantity
Raw materials through finished products
Most raw materials, intermediate ingredients, and finished products are supported. Matrix-specific preparation, feasibility, reporting basis, and accreditation needs are confirmed during intake. Call or email the laboratory before submitting less than 2 grams.
Mass-basis reporting
For samples under 2 grams, contact the laboratory before shipping so feasibility can be confirmed.
mg/mL reporting
Send at least 5 mL when results are requested on a volume basis.
mg/unit reporting
Send at least 5 individual units or servings when results are requested per unit.
Turnaround
Five business days standard
Expedited turnaround as fast as 12 hours may be available for an additional fee. Call or email the laboratory for feasibility and the detailed expedite fee schedule.
Have a time-sensitive project?
Include the matrix, sample count, requested reporting units, and deadline so the laboratory can evaluate the fastest available schedule.
Quality Context
Validated in-house
The method is validated in-house. Cora Science is accredited in the field of testing to ISO/IEC 17025:2017 by Perry Johnson Laboratory Accreditation, Inc. (PJLA), Accreditation #116374.
Accreditation applies only to activities listed in the laboratory's current accreditation scope; not every service or matrix is necessarily within scope. State any project-specific accreditation requirement during quote review.
Review quality and accreditation informationMarket & Specification Context
Match the reported result to the specification language
Ashwagandha specifications may use different constituent lists and calculation definitions. Include the exact claim or specification language during intake.
Calculation definition
The profile's calculated result is limited to the eight compounds listed here. If a specification requests total withanolides or another defined constituent calculation, identify the exact analytes and convention before submission.
Material context
Describe whether the sample is root, leaf, an extract, a blend, or a finished product and provide the label claim and requested reporting basis.
Analytical scope
The quantitative profile does not by itself establish botanical identity or certify product compliance. Share any separate identity or market requirement during quote review.
FAQ
Planning a submission
What does Ashwagandha Withanolides report?
Ashwagandha Withanolides covers the 8 analytes listed on this page with quantitative reporting. Share any project-specific specification or reporting convention during quote review.
What matrices can be submitted?
Most raw materials, intermediate ingredients, and finished products are supported. Unusual formats, samples below two grams, and matrix-specific reporting or accreditation requests should be discussed with the laboratory before submission.
What reporting units are available?
The default is weight by weight percent (w/w%). Reporting may also be requested as mg/g, mg/mL, or mg/unit when the submission supports the requested basis.
How quickly are results available?
Standard turnaround is five business days. Expedited turnaround as fast as 12 hours may be available for an additional fee after the laboratory confirms feasibility.
